A pole mounted dual axis solar tracking apparatus has a main mounting member [13] in a fixed primary north-south axis which is inclined to accommodate geographical latitude and a cross arm [16] fixed to the main mounting member and defining a secondary east-west axis. A support frame [15] for PV panels, solar reflectors etc. is pivoted to the cross arm to enable the support frame to tilt over the secondary east-west axis. The apparatus is highly efficient due to its ability to sweep through the shape of two conjoined cones. The apparatus operates with close to the efficiency of a dual axis tracker but with the simplicity of a single axis tracker. |
